Xfinity ID:
Why do I need an Xfinity ID?

To make sure everyone gets the same smooth, secure experience, we’re requiring all customers to create an Xfinity ID.

Creating one is quick and easy—plus, it allows you to manage your account anytime, from anywhere, with a single login:

  • Refill your services on the go.
  • Check your expiration dates.
  • Make payments.
  • Find retailers nearby.
  • Keep up with the latest offerings and promotions.
What is an Xfinity ID?

Your Xfinity ID gives you access to everything from managing your account to enjoying your entertainment. Your ID can be your email address, the mobile phone number you use to sign in, or your username.

Can I use my previous login info?

No, you’ll need to create an Xfinity ID.

In the past, you may have created an 8-digit pin that you used with your phone number to log in to your Xfinity Prepaid Services account. You will no longer be able to log in using that information.

To access and manage your account, you must create an Xfinity ID, which will allow you to log in using your email address and a new password of your choice.

How do I know if I already have an Xfinity ID?

If you’re not sure whether or not you’ve already created an Xfinity ID, you have two options:

  1. Try to create an Xfinity ID.
  2. Try to log in.

In either case, you’ll be prompted to enter your information and the system will detect whether that information is already associated with an existing Xfinity ID.

If it is, we’ll prompt you to log in. There are options to help you retrieve or change your password along the way in case you forgot yours.

If the system does not detect an existing Xfinity ID associated with your information, just follow the instructions to create one.

Need to create an Xfinity ID?

If you don’t yet have an Xfinity ID, you can create one.

You’ll need to self-identify by providing any of the following:

  • Comcast account number and street address, or
  • Comcast account number and phone number, or
  • Last four digits of your Social Security Number, date of birth and phone number.
  • Click the triangle icon next to Use Social Security Number (last 4 digits) to reveal date of birth and phone number.

Note: If you're an Xfinity Internet customer accessing the tool from your home, you'll only be asked for the phone number associated with your account.

Use the online password reset tool to change or reset your password.

I forgot my Xfinity ID or password.

Your Xfinity ID is typically your email or mobile phone number. If you don’t remember your Xfinity ID, you can look it up with the online lookup tool.

What if I no longer need my equipment or want to recycle it?

Should you need to return your Comcast equipment or if you no longer need the device, please drop it off at a Customer Service Center or Xfinity Store. Find a Customer Service Center or Xfinity Store location near you.
